I’m not qualified to give a correct answer to this , no one on earth is yet.
In my opinion the similarity is the problems that any form of ‘solution’ would cause , the American people won’t let the government take the guns off them without chaos (there are strong arguments on both sides on whether to keep or take guns away , I recommend this video to see the argument for guns which usually isn’t understood.

Similarity in the UK you can’t ‘ban’ knives for obvious reasons. I believe efforts have been put in to carry out more stop and search to people , and this only brings problems such as racial tension and more violence (if a police officer tries to search a person that is carrying a knife , it is pretty likely that they aren’t in a stable way therefore would be more likely to use it.
The US claims to be a superpower because they are , all things considered , yes they have horrific domestic issues , but it could be argued that other countries have them worse , or maybe not , for example some European countries usually thought of being nothing are some of the best places to live for a lot of people , but they aren’t a superpower because of the size and where they put their money.
Overall it’s an insanely complex issue which is made more difficult when people blurt our ‘ban all guns’ or ‘life sentences for having a knife’ the best way is always to question everything and take into account what everyone is saying , no matter how idiotic they are , as if it is , then the counter argument should be easy to give , if someone’s trying to suppress another , often the suppressor doesn’t want the suppressed to be heard , why ?
